JAMES O. SLAFTER, OF MINNEAPOLIS, ASSIGNOR OF ONE-HALF HIS RIGHT TOCLARENCE NASH, OF ST. PAUL, MINNESOTA.

IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 176,368, dated April18, 1876 application filed a February 25, 1876.

To all whom it may concern:

Be it known that I, JAMES C. SLAFTER, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Oil'Cans; and I do hereby declare that the following isa full, clear, and exact description thereof,

which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

Figure 1 is an elevation of an oil-can embodying my invention, with aportion of the nozzle broken away. Fig. 2 is a detached view of thevalve, and Fig. 3 represents the blank or plate of metal from which thevalve is made.

The object of my invention is to prevent the oil which trickles down theoutside of the nozzle or deliverytip of an oil-can from passing to theoutside of the body of the can, where it is liable to soil articles withwhich it (the can) is brought in contact.

To this end the invention consists in combining with such nozzle adripcup or disk, to receive the oil which flows down the outside of thenozzle, a perforation to permit the oil thus collected to pass into thebody of the can, and an automatic valve arranged within said nozzle, andoperating to prevent the oil from flowing out through the abovementionedperforation when the can is in an inverted position, as will be fullyexplained.

In the drawings. A is the body of the can, the neck B of which isprovided with a screw thread, into which the nozzle 0 screws in anyusual manner. The nozzle 0 is of the usual tapering form, and has a dripcup or disk, D, attached thereto. Immediately above this cup there is aperforation, 0, through the nozzle. E E is a valve, the body or upperpart E of which is made hollow, tapering in form, and

of such size as to fit accurately the inner surface of the nozzle at thepoint where the hole cis located. 9 is a slot in the valve. (See alsoFig. 3.) Ihe lower end E of the valve is bent at about a right angle tothe body E, and is loaded or weighted, for a purpose which will beexplained. a is a pin projecting from the inner surface of the nozzle,and passing through the slot e in the valve, thus keeping said valve inproper position and limiting its movements. The valve is made from asingle piece or blank of metal, Fig. 3, formed into the requisite shapeby any usual or preferred method of manufacture. When the can isinverted for the purpose of delivering the oil through the nozzle, thevalve moves toward the small end of the nozzle and covers theperforation c, (as indicated in Fig. 1,) thus effectually preventing anyescape of oil at this point. When, however, the can is returned to anupright position, the valve falls back to the position indicated bydotted lines, thus uncovering the opening 0, and permitting such oil asmay drip or pass down the outside of the nozzle to enter the body of thecan. In addition to the effect of the weighted end E of the valve incausing it to move over and from the opening 0, the oil, in flowing intoand out of the nozzle 0, encounters this end, which is at right anglesto the nozzle, and thus insures that the valve shall be properly moved.

What I claim is- In an oil-can, the combination of the nozzle 0,provided with a perforation, c, the dripcup D, and the tubular slidingvalve E E, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
